Question

Use the information given below to find the​ P-value. Also, use a 0.05 significance level and state the conclusion about the null hypothesis​ (reject the null hypothesis or fail to reject the null​ hypothesis). The test statistic in a​ left-tailed test is zequalsnegative 1.23.

What is the​ P-value? ​P-valueequals nothing ​(Round to four decimal places as​ needed.) State the conclusion about the null hypothesis. Choose the correct answer below.

A. Reject the null hypothesis. The​ P-value is less than the level of significance.

B. Fail to reject the null hypothesis. The​ P-value is greater than the level of significance.

C. Fail to reject the null hypothesis. The​ P-value is less than the level of significance.

D. Reject the null hypothesis. The​ P-value is greater than the level of significance

Answer 1

Answer:

(B Fail to reject the null hypothesis. The​ P-value is greater than the level of significance.

Step-by-step explanation:

The null hypothesis is rejected, if P-value is less than the level of significance.

Here, it is provided that the test is left tailed and z score is -1.23.

From, the table of negative score, the P-value for left tailed test is 0.1093.

Since, the P-value (0.1093) is greater than the level of significance (0.05). The null hypothesis is not rejected.

Hence, the correct option is (B), Fail to reject the null hypothesis. The​ P-value is greater than the level of significance.
